Abstract
BACKGROUND The COVID-19 outbreak and consequent physical distance measures implemented worldwide have caused significant stress, anxiety, and mental health implications among the general population. Unemployment, working from home, and day-to-day changes may lead to a greater risk of poor mental health outcomes. OBJECTIVE This paper describes the protocol for a web-based cross-sectional study that aims to address the impact of the COVID-19 pandemic on mental health. METHODS Individuals from the general population aged 18 years or more and living in Portugal were included in this study. Data collection took place between November 10, 2020, and February 10, 2021. An exponential, nondiscriminative, snowball sampling method was applied to recruit participants. A web-based survey was developed and shared on social media platforms (eg, Facebook, Instagram, Twitter, LinkedIn, and WhatsApp groups) and through e-mail lists for recruitment of the seeds. RESULTS Data analysis will be performed in accordance with the different variables and outcomes of interest by using quantitative methods, qualitative methods, or mixed methods, as applicable. A total of 929 individuals had completed the web-based survey during the 3-month period; thus, our final sample comprised 929 participants. Results of the survey will be disseminated in national and international scientific journals in 2021-2022. CONCLUSIONS We believe that the findings of this study will have broad implications for understanding the psychological impact of the COVID-19 pandemic on Portuguese residents, as well as aspects related to the informal economy. We also hope that the findings of this study are able to provide insights and guidelines for the Portuguese government to implement action. Finally, we expect this protocol to provide a roadmap for other countries and researchers that would like to implement a similar questionnaire considering the related conclusions.

Abstract
Abstract
Background
COVID-19 pandemic has been affecting population’s health and economies, in which food insecurity appears as important concern, particularly considering its associations with mental health and adverse behaviours. This study explored the relationship between food insecurity and mental health features and behaviours in adults from Portugal.
Methods
A cross-sectional study using data from an online survey was performed, including Portugal’s residents aged ≥18 years. Data on sociodemographics, behaviours, mental health features and food security status were collected. Food security status was evaluated with the United States Household Food Security Survey Module: Six-item Short Form. Chi-square test or Fisher's exact test, as appropriate, were used to explore the relationship between food security status and categorical variables.
Results
Food insecurity prevalence was 6.8%; showed to be significantly higher among less educated individuals (≤12 years of schooling) (p<0.001), those who were employed and remained since the beginning of the pandemic (p<0.001) and among those reporting need to be careful about expenses (p<0.001). Comparing to individuals who were food secure, food insecure participants were more likely to smoke (p=0.009), to report depressive symptoms (p<0.001) and anxiety (p<0.001), measured by the Hospital Anxiety and Depression Scale.
Conclusions
From the present study, it can be concluded that the COVID-19 pandemic can affect food security in different subpopulations.
Key messages
The findings of this study have several implications for health policy and reinforce the need for investment in contexts of populations vulnerable to food insecurity

Abstract
COVID-19 vaccines are considered promising agents in the control of the pandemic. Although their safety was assessed in randomised clinical trials, severe adverse events (AEs) have been reported after large-scale administration. This study aims to evaluate thromboembolic AEs reported after vaccination in a real-world context and how they led to the interruption of vaccination campaigns. We also review the benefits and risks of the vaccines approved in the European Union and provide recommendations. A review of the literature was performed using Medline/PubMed electronic database as well as institutional and pharmacovigilance official reports. Our findings show that vaccine-induced prothrombotic immune thrombocytopenia has been suggested as a very rare AE associated with viral vector vaccines. Unusual thrombotic events combined with moderate-to-severe thrombocytopenia were reported mainly in women under 60 years of age. As safety signals emerged, Vaxzevria and Janssen´s COVID-19 vaccine campaigns have been paused while investigations proceed. On the other hand, the number of deep vein thrombosis and pulmonary embolism reports have not increased. Post-marketing surveillance indicated that mRNA vaccines are safe and should continue to be used. The thrombotic events report rate is not increased in people over 60 years. As they are at greater risk for COVID-19 complications and death, no vaccine restrictions are recommended in this group. Risk factors for vaccine-induced prothrombotic immune thrombocytopenia should be established so that evidence-based decisions can be made. Systematic monitoring of COVID-19 vaccine safety is essential to ensure that the benefits of vaccination outweigh the risks.

Abstract
Abstract
Background
During these unprecedented times, individuals who experience the sudden death of a family member or friend, already miss the anticipatory grief and are now also prevented from a proper farewell. This study aimed to address prolonged grief disorder since the beginning of the COVID-19 pandemic
Methods
A virtual snowball sampling survey was disseminated through social networking channels. The study enrolled participants from general resident population in Portugal with ≥18 years. Characteristics of the sample were summarized using descriptive statistics. Anxiety and depression symptoms are described by absolute and relative frequencies and compared through the Chi-square test.
Results
A total of 929 participants completed the survey; 17.9% (n = 166) have lost someone since the beginning of the pandemic, making our final sample. Most were female (66.9%); median age of 35 years and 70.5% had a high education degree. Participants who had lost a grandparent consisted of 28.3% of the sample, father and/or mother 9.0%, and a friend 22.3%. We found a prevalence of 30.7% of anxiety symptoms and 10.2% of depression symptoms (p = 0.030). Also, 16.8% have had a high score on the PG13, which show that these people can mourned for longer periods.
Conclusions
Paying the last tribute to a loved one is a mental health gesture that allows individuals to make amends and reconcile with life.
Key messages
The need arises to give timely attention to the psychological consequences due to the COVID-19 pandemic concerning grief

Abstract
Background: Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) have been increasingly available in Europe. Due to the high burden of HIV in key populations, these could benefit from their use. In 2016, in Portugal, an open, non-interval, prospective cohort study was established in a network of 26 community-based voluntary HIV/STI counseling and testing centers. Data collected included questions on PEP and PrEP knowledge and use. We aimed to estimate the proportion of PEP and PrEP knowledge and its use among key populations, visiting the centers between 2016 and 2019. Method and results: Individuals who self-identify as being among at least one key population for HIV, men who have sex with men (MSM), people who inject drugs (PWID), sex workers (SW), migrants, and male-to-female transgender individuals (MTF), responded to questions on PEP and PrEP knowledge and use while waiting for their test results between 2016 and 2019 (n = 12,893 for PEP; n = 10,973 for PrEP). Reported knowledge was low in all key populations for both tools: 15.7% of respondents reported knowing about PEP and 10.9% about PrEP over the course of 4 years. PEP was used by 1.8% and PrEP by 0.4% of the respondents, MSM being 88.9% of PrEP users, and 52.8% of PEP users. Multivariate logistic regression showed multiple factors associated with knowing the tools, including age, education, country of birth, gender, year of test, having a reactive HIV test in the same visit, reporting an STI or condomless sex in the last 12 months, and identifying with being MSM or SW. Conclusions: Knowledge and use of PEP and PrEP remain low among key populations in Portugal. The need remains to increase knowledge and use among those at risk for HIV infection.

Abstract
STUDY QUESTION Does the time elapsed between oocyte pick-up (OPU) and denudation or injection affect the probability of achieving a live birth (LB) in ICSI cycles? SUMMARY ANSWER Prolonged oocyte culture before denudation (>4 h) was associated with an increase in clinical pregnancy (CP), LB and cumulative LB (CLB) rates when compared with earlier denudation timings. WHAT IS KNOWN ALREADY Oocyte maturation is a complex and dynamic process involving structural and biochemical modifications in the cell necessary to support fertilization and early embryo development. While meiotic competence is easily identifiable by the presence of an extruded first polar body, cytoplasmic maturation cannot be assessed microscopically. Culturing oocytes with their surrounding cumulus cells (CCs) prior to ICSI can enhance the completion of in vitro cytoplasmic maturation; conversely, prolonged culture may induce cell degeneration. The optimal culture intervals prior to oocyte denudation and/or injection have not yet been established and may prove relevant for the improvement of ICSI reproductive outcomes. STUDY DESIGN, SIZE, DURATION This is a single-centre retrospective cohort analysis of 1378 ICSI cycles performed between January 2005 and October 2018. Data were categorized according to: (i) the time interval between OPU and denudation (<3 h, 3-4 h and ≥4 h), (ii) the time interval between denudation and ICSI (<1.5 h, 1.5-2 h, ≥2 h) and (iii) the time interval between OPU and ICSI (<5 h, 5-6 h and ≥6 h). The effect of these timings on fertilization, CP, LB and CLB rates were compared. The culture intervals between different procedures were dependent exclusively on laboratory workload. PARTICIPANTS/MATERIALS, SETTING, METHODS ICSI cycles performed in women younger than 40 years old using autologous gametes with at least one metaphase II injected oocyte were included. The effect of oocyte culture duration prior to denudation and injection of the oocytes was compared using multivariable regression accounting for potential confounding variables. MAIN RESULTS AND THE ROLE OF CHANCE Fertilization and oocyte damage rate after ICSI was found to be independent of the time interval to denudation (<3 h, 3-4 h and ≥4 h) and/or injection (<5 h, 5-6 h and ≥6 h). Extending oocyte culture before denudation significantly improved CP (29.5%, 42.7% and 50.6%, respectively), LB (25.1%, 34.4% and 40.7%, respectively) and CLB rates (26.0%, 36.1% and 42.2%, respectively), particularly if the time interval was at least 4 h. Additionally, LB (31.7%, 35.8% and 27.4%, respectively) and CLB rates (34.2%, 36.6% and 27.7%, respectively) were also dependent on the time from OPU to injection. LIMITATIONS, REASONS FOR CAUTION This study is limited by its retrospective nature and potential unmeasured confounding cannot be excluded. Furthermore, the effect of even shorter or longer periods of culture before denudation and/or injection were not evaluated and should not be extrapolated from these results. WIDER IMPLICATIONS OF THE FINDINGS Our findings propose new evidence of a previously unrecognized protective effect of the CCs-oocyte interactions in human ART, raising the question of a possible downstream effect in embryogenesis which significantly affects LB rates. Additionally, this is the first study to suggest a negative effect of further extending culture before ICSI on LB and CLB rates, thus potentially allowing for the narrowing of an optimal ICSI time interval. Simple strategies such as the establishment of more effective time frames to perform these procedures and adjusting laboratory practice may prove beneficial, ultimately improving ICSI reproductive outcomes.

Abstract
Infectious diseases, such as tuberculosis (TB) and the novel coronavirus (COVID-19) relate to environmental factors, understanding of which is essential to inform policy and practice and tackle them effectively. The review follows the conceptual framework offered by the World Health Organization Commission on Social Determinants of Health (defined as “all those material, psychological and behavioural circumstances linked to health and generically indicated as risk factors’ in the conventional epidemiological language”). It describes the social factors behind TB and COVID-19, the commonalities between the two diseases, and what can be learned so far from the published best practices. The social determinants sustaining TB and COVID-19 underline the importance of prioritising health and allocating adequate financial and human resources to achieve universal health coverage and health-related social protection while addressing the needs of vulnerable populations. Rapid and effective measures against poverty and other major social determinants and sources of inequality are urgently needed to develop better health in the post-COVID-19 world.

Abstract
THE POISONOUS GARDEN: THE CHEMISTRY BEHIND THE INTOXICATION BY DOMESTIC ORNAMENTAL PLANTS. In times of the COVID-19 pandemic, despite the fact families have spent more time together, the job demands and commitments that adults have now brought into their homes may mean their attention has been taken away from their children. This, combined with the absence of older family members or domestic helpers that assist in looking after the children has left them potentially more exposed to domestic accidents. Data from the National Toxic-Pharmacological Information System indicate that two-thirds of domestic intoxications with plants (usually the ornamental ones) occur in children. These accidents can be caused either by inhalation, contact with the skin, eyes and mucous membranes, as well as by ingestion. The toxicity of ornamental plants is due to the presence of substances such as oxalic acid and its highly irritating salts, alkaloids, glycosides, flavonoids, and toxic terpenes, among several other classes of secondary metabolites. In the present study, we carried out a survey of the main ornamental plants used in the country and analyzed the toxic substances that can cause numerous conditions from dermatitis in milder cases to death in more severe cases.

Abstract
Abstract
Background
Antiretroviral therapy (ART) has the most effective treatment for people with HIV, but its effectiveness depends on the individual medication adherence. Morisky Medication Adherence Scale (MMAS-8) is one of the most widely used scales to assess patient adherence. Thus, we aimed to validate a Portuguese version of MMAS-8 and determine its psychometric properties in HIV positive patients.
Methods
A cross-sectional survey was conducted in Centro Hospitalar Universitário São João (Porto, northern Portugal) at the infectious diseases department. After authorization to use the scale - granted by the author - and, a standard forward-backwards procedure to translate MMAS-8 to Portuguese, the questionnaire was applied to 233 patients with HIV doing ART. Reliability was assessed using Cronbach's alpha and test-retest reliability. Three levels of adherence were considered: 0 to < 6 (low), 6 to < 8 (medium), 8 (high).
Results
In the studied sample, the mean age was 45.03 years (SD = 11.63), 80.3% men, 19.3% women and 1 transgender, and 53.8% had ≤9 years of education. The mean number of prescribed ART per patient was 1.76. The mean score for the medication adherence scale was 7.29 (SD = 6.74). For the reliability analysis, 12 patients were excluded due to missing data (n = 221). Regarding the level of adherence, 22.5% were low adhering, 71.6% medium and 5.9% high. Corrected item-total correlations showed that 1 item does not correlate very well with the overall scale and was dropped. Scale reliability analysis for the remaining 7 items revealed an overall Cronbach's alpha of 0.661. Women had a protective effect on adherence (OR = 0.31;95%CI:0.15-0.66). Number of years doing ART, age of participants, and type of residence didn't show to be correlated with adherence.
Conclusions
MMAS-8 is a reliable and valid measure to detect patients at risk of non-adherence. A satisfactory Cronbach's alfa (0.661) was obtained. In general, adherence to medication was medium or high.
Key messages
This scale can be applied nationwide in other different hospitals, as it could serve as a tool for measuring adherence to ART that can allow for better health care to the ones that are low adhering. A Portuguese version of the MMAS-8 was created for measuring adherence to ART that maintained a similar structure to the original MMAS-8 and good psychometric properties.

Abstract
Abstract
Recently, it became clear that undetectable equals untransmittable (U=U), stressing the importance of engaging in medical care and adhering to antiretroviral therapy. HIV testing and counselling (HTC) are offered in different settings and can be an opportunity to inform people. We aimed to understand if HIV testing history, including recency, place and, result, was associated with U=U knowledge.
We used data from 2242 MSM living in Portugal participating in EMIS 2017 that answered if they already knew that “A person with HIV who is on effective treatment (called 'undetectable viral load') cannot pass their virus to someone else during sex”, opting of 5 possible answers, dichotomized in “I already knew” vs. any other option. Regarding HIV testing history, participants were categorized as follows:1. HIV positive; 2. HIV negative and last test ≤12 months in a community setting; 3. HIV negative and last test ≤12 months in a medical setting, and 4. never tested for HIV or last test >12 months or tested in other settings (reference). Logistic regression models were fitted to estimate crude and city size and education-adjusted associations.
The median (P25; P75) age of participants was 34 (25; 43) years. No significant statistical association was found with age or current occupation. Those with more years of education and living in a big or very big city were more likely to know that U=U (aOR:1.55; 95%CI:1.20-1.99 and aOR:1.26; 95%CI:1.04-1.53, respectively). Considering HIV testing history and diagnosis, men with diagnosed HIV (aOR:6.33; 95%CI:4.50-8.90), those who had the last test in community setting (aOR:2.44; 95%CI:1.87-3.17) and those who had the last test in a medical setting (aOR: 1.57; 95%CI:1.26-1.95) were more aware of U=U than those not tested in the last 12 months.
Our results suggest that there is a gradient of U=U knowledge associated with HIV testing history among MSM. Efforts should focus on improving counselling about U=U at all HIV testing settings.
Key messages
The knowledge of U=U seems to be associated with the place, recency and result of the last HIV test. Counselling should focus on the best evidence available at all HIV testing settings, to inform and empower the individuals.

Abstract
Family farming has been on the agenda worldwide. Portugal is no exception. Act No. 64/2018, published in 2018, establishes the Family Farming Statute. Its preponderance in food and in the sustainability of families and territories has been reinforced by the sustainable development paradigm. However, competitiveness constraints assigned to the production system is often seen as an obstacle. Combining the theoretical frameworks of integrated agriculture and work organizations, we offer a lean sociological perspective on family farms producing lettuce. We concluded that their production system is characterized by a set of innovative practices very close to a lean approach. However, there is room for improvements in a production system that seems to maintain a family-based workforce and traditional know-how.

Association of prenatal maternal perceived stress with a sexually dimorphic measure of cognition in 4.5-month-old infants. Neurotoxicol Teratol 2020; 77:106850. [PMID: 31812786 PMCID: PMC6980724 DOI: 10.1016/j.ntt.2019.106850] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 11/21/2019] [Accepted: 12/04/2019] [Indexed: 01/02/2023]
Abstract
Maternal prenatal stress can adversely impact subsequent child neurodevelopment, but little is known about its effect on cognitive development in infancy. This analysis of 107 infants from a prospective birth cohort assessed whether prenatal stress disrupts sexually dimorphic performance typically observed on a physical reasoning task. Maternal stress was assessed at 8-14 and 33-37 gestational weeks using the Perceived Stress Scale. Stress was defined as: low (scores below the median at both times), medium (scores above the median at one of the two times), and high (scores above the median at both times). At 4.5 months infants saw videos of two events: one impossible and the other possible. In the impossible event a box was placed against a wall without support underneath. In the possible event the box was placed against the wall, supported by the floor. Looking time at each event was recorded via infrared eye-tracking. Previous literature has shown that, at 4.5 months of age, girls typically look significantly longer at the impossible than at the possible event, suggesting that they expect the unsupported box to fall and are surprised when it does not. Boys tend to look equally at the two events suggesting that they do not share this expectation. This sex difference was replicated in the current study. General linear models stratified by sex and adjusted for household income, maternal education, mother's age at birth, infant's age at exam, and order of event presentation revealed that girls whose mothers reported high perceived stress during pregnancy had shorter looking time differences between the impossible and possible events than girls whose mothers reported low perceived stress (β = -7.1; 95% CI: -12.0, -2.2 s; p = 0.006). Similar to boys, girls in the highest stress category spent about the same amount of time looking at each event. For boys, there were no significant looking time differences by maternal stress level. This finding suggests prenatal stress is associated with a delay in the development of physical reasoning in girls.

[PMID: 31892183 PMCID: PMC6983106 DOI: 10.3390/s20010170] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2019] [Revised: 12/15/2019] [Accepted: 12/20/2019] [Indexed: 11/16/2022]
Abstract
The development of efficient sensing technologies and the maturation of the Internet of Things (IoT) paradigm and related protocols have considerably fostered the expansion of sensor-based monitoring applications. A great number of those applications has been developed to monitor a set of information for better perception of the environment, with some of them being dedicated to identifying emergency situations. Current IoT-based emergency systems have limitations when considering the broader scope of smart cities, exploiting one or just a few monitoring variables or even allocating high computational burden to regular sensor nodes. In this context, we propose a distributed multi-tier emergency alerting system built around a number of sensor-based event detection units, providing real-time georeferenced information about the occurrence of critical events, while taking as input a configurable number of different scalar sensors and GPS data. The proposed system could then be used to detect and to deliver emergency alarms, which are computed based on the detected events, the previously known risk level of the affected areas and temporal information. Doing so, modularized and flexible perceptions of critical events are provided, according to the particularities of each considered smart city scenario. Besides implementing the proposed system in open-source electronic platforms, we also created a real-time visualization application to dynamically display emergency alarms on a map, demonstrating a feasible and useful application of the system as a supporting service. Therefore, this innovative approach and its corresponding physical implementation can bring valuable results for smart cities, potentially supporting the development of adaptive IoT-based emergency-aware applications.
